2 Claims. (c1. -262) This invention relates to edge supporting devices for mattresses. 7

Among the objects of the present invention, it

is aimed to provide an edge supporting device 5 for a mattress which will facilitate pressing the mattress edge down to its'full depth without interference and according to which not only a maximum raised position of the edge is positively determined but also a maximum laterally extended position of the edge is positively determined.

It is still another object of the present invention to'provide an improved edge supporting device for a mattress which can be manufactured at low cost and which has a minimum number of 5 parts.

These and other features, capabilities and ad vantages of the invention will appear from the subjoined detail description of one specific embodiment thereof illustrated in the accompanying drawing in which Figure l is a plan of a mattress equipped with the improved edge supporting devices constituting the present invention;

Fig. 2 is an enlarged fragmental elevational view along the line 22 of Fig. 1; and

Fig. 3 is an enlarged fragmental elevational view, similar to Fig. 2, but showing the edge partially depressed.

Edge supporting devices constituting the present invention are illustrated as equipped on a mattress I having an upper outer rectangular frame 2 to which the upper edges of the outer row of coil springs 3 are connected. The lower edges of the outer row of coil springs 3 are preferably as indicated mounted on the rectangular frame 4.

The longitudinally extending sides 5 and 6 of the frame 4 are preferably connected to one another and braced by the crosspieces 1. Each of these crosspieces 1 consists preferably of a flat bar extending edgewise across the bottom of the mattress, see the portion 8, and which crosspieces preferably have their ends bent to form the horizontally extending portions 9 which are secured to the sides 5 and 6 of the frame 4 in the present instance.

Between the outer rows of coil springs 3, there are arranged the inner coil springs In which have their lower ends connected to the portions 8 of the bars I and their upper ends connected to one another and to the outer row of coil springs 3 as shown in Fig. 1.

The edge supporting devices constituting the present invention each consist essentially of a fixed supporting bar H, preferably angle iron, having its horizontally extending portion secured to one of the sides 5 or 6 of the frame 4. The bar I I extends inwardly from the side 5 or 6.

To the vertically extending portion l2 adjacent its outer end, there is pivotally connected the short flat link l3, the upper end of which is piv- "5 otally connected to the lever 14. The lever I4 is preferably composed of flat stock and is provided with an elongated slot I5 to receive the pin l6 formed in the vertically extending portion l2 of the bar ll. 10

The lower end of the lever 14 extends down below and inwardly from the bar II and is connected bythe spring H with the pin l8 extending down'from the horizontally extending portion of the bar ll outwardly of the pin I6. 15

- The upper end IQ of the lever I4 is bent over at right angles to the main portion of the lever 14 and it has its extreme upper end bent around the frame 2, this end of the lever [4 being preferably formed into a closed loop as indicated at 20. 20

In the present instance, there are only illustrated four of the edge supporting devices on the mattress illustrated in Fig. 1 but it is of course obvious that more or less may be provided as desired.

It is also obvious that these edge supporting devices may be secured not only to the sides of the mattress but also to the ends or to'the ends alone without departing from the general spirit of the invention.

With these edge supporting devices, it will appear that the springs I! will cooperate with the links l3 not only to press the levers 14 to a predetermined position so that their upper looped M ends 20 will assume a positively predetermined upper outer position, determined in part at least by the location of the lower ends of the slots l5 relative to the lengths of thelinks l3 and levers i l and positions of these several parts relative to the mattress to which they are attached.

It will appear also from the foregoing that the edge frame 4 may be depressed down to the full extent of contraction of the springs 3 without interference by any of the edge supporting devices. 1

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.

I claim:

1. The combination with a mattress having an upper outer rectangular frame composed of round stock, of a, lower smaller rectangular frame composed of angle iron having its horizontally exflange disposed at its lower side, the outer end of the horizontally extending flange of said bar being secured to the horizontal flange portion of one of the longitudinally extending. sides of said lower frame', a pin formed at the inner end of the vertically extending flange of said bar, an abutment extending downwardly from the horizontally extending flange of said bar and spaced from the inner end thereof, a lever: composed of flat stock and having a slot dividing the same into a short arm and a long arm, the slot re-' ceiv'mg' said pin with the short arm of said lever extending inwardly below said bar, a spring connecting the free end of said short arm with said abutment, a link composed of flat stock and pivotally connecting the long arm of said lever with the vertically extending flange of said bar, the upper portion of said long arm being bent at right angles:- to the lower portion thereof and being formed into a loop at its extreme upper end ,to receive one of the longitudinally extending sides of' said upper frame and forming a pivotal connectionwith the same.

2- .Ihe combination with a mattress having an upper outer rectangular frame composed of round stock, of a lower smaller rectangular frame composed of angle iron having its horizontally extending flange at its upper end' and normally offset inwardly relative'to said upper frame, inner coil springs separating and operatively connecting said upper frame to said lower frame, edge supporting devices permitting the depression of said upper frame at least one half the normally extended distance from said lower frame, each having a horizontally extending bar composed of angle iron and having its horizontally extending flange disposed at its lower side, the outer end of the horizontally extending flange of said bar being secured to the horizontal flange portion of one of the longitudinally extending sides of said lower frame, a pin formed at the inner end of the vertically extending flange of said bar, an

abutment extending downwardly from the horizontally extending flange of said bar and spaced from the inner end thereof, a lever composed of flat stock and having a slot dividing the same into a short arm and a long arm, the slot receiving said pin with the short arm of said lever extending inwardly below said bar, a coil spring connecting the free end of said short arm with said abutment, a link composed of flat stock and pivotally connecting the long arm of said lever with the vertically extending flange of said bar, the upper portion of said long arm being bent at right angles to the lower portion thereof and being formed into a loop at its extreme upper end to receive one of the longitudinally extending sides of said upper frame and forming a pivotal connecticn with the same, the vertically extending flange of said. bar having its flat face disposed adjacent to and in sliding engagement with the main flat faces of said link and the lower portion of said lever, and said link and the lower portion of said lever having their main flat faces disposed adjacent to one another and in sliding engagement with one another.
